Abstract (en)

[origin: EP2783885A1] The device (10) has a heavy body (16) connected around a portion (Sp) of coils (18) of a helicoid spring (12) between spring ends (22, 24) of the spring. The body is connected to the portion such that the body cannot move along the portion under the function of the device, and cannot swivel around an axis (Sa) of the portion. The body is provided a core made of one material, and an envelope made of another material e.g. polymer material such as elastomer. The body has a mass dependant on oscillatory modes of the spring to carry out a shift and/or an attenuation of one mode of the coils.
